Distributed power and capacitor optimization can effectively reduce power loss and improve voltage stability.On this basis, the establishment of a system of network optimization model with minimal losses as the objective function, It use sensitivity way to solve the position of distributed power and capacitors, and use heuristic method to solve the capacity configuration . The last, in IEEE-33 test system node, through analysis and comparison of several typical case, The result show minimize power loss within ideal voltage and to reduce the distribution lines load.
